Microneedle bio-sampling apparatus

摘要

There is provided a microneedle bio-sampling apparatus including: an bio-sampling body enabling a microneedle to be inserted into human skin; and a blocking unit installed in the bio-sampling body and preventing the microneedle from moving to the skin again to prevent repeated bio-sampling by the microneedle. Since the microneedle bio-sampling apparatus is configured to prevent repeated bio-sampling of a single-use microneedle, secondary infection to other part of a human body or a different person due to blood, human anatomy, or the like, that may remain in a microneedle after the microneedle is used once otherwise in case of repeated bio-sampling of a microneedle, can be prevented.

主权项

1. A bio-sampling apparatus comprising:
a bio-sampling body configured to enable insertion of a needle into a sample; and a blocking unit installed in the bio-sampling body, wherein the blocking unit is configured to prevent the needle from repeatedly moving into the sample, wherein the bio-sampling body comprises:
an external cover having a hollow connecting openings formed in a plurality of sides of the external cover;a pressing unit having one side in which the needle is installed, wherein the pressing unit is configured to move toward the sample along the hollow; andan elastic unit fixed to the external cover, connected to the pressing unit, wherein the elastic unit returns the pressing unit, having moved toward the sample, to an original state of the pressing unit when pressure applied to the pressing unit is removed, wherein the blocking unit comprises:
a film member fixed to the pressing unit and surrounding the needle;a film cover covering the film member and having a size corresponding to an edge of the pressing unit; anda blocking member fixed to the external cover and configured to elastically press the film cover, penetrating through the film member to extend inwardly when the film cover is removed from a position covering the film member, and wherein the blocking member prevents the pressing unit from repeatedly moving toward the sample, thereby preventing repeated bio-sampling.
